Chapter 1: Overview Features The AT-FS708/POE Fast Ethernet switch is an unmanaged switch with the following features: Eight 10/100Base-T twisted-pair ports with Power over Ethernet (PoE) capability Auto-Negotiation and Auto MDI/MDI-X on all twisted-pair ports One small form-factor pluggable (SFP) port to use as an uplink port with support for 1000Base-T copper or fiber SFP modules Up to 8K MAC address table Backpressure and IEEE802.
AT-FS708/POE Fast Ethernet Switch Installation Guide Port Descriptions The following sections describe the types of ports on the AT-FS708/POE Fast Ethernet switch: Twisted Pair Ports “Twisted Pair Ports,” next “SFP Port” on page 17 The AT-FS708/POE Fast Ethernet switch features eight 10/100Base-T twisted-pair ports. The twisted-pair ports feature 8-pin RJ-45 connectors. For the port pinouts, refer to “RJ-45 Twisted Pair Port Connectors and Pinouts” on page 52.
Chapter 1: Overview The SFP transceiver is a fast and easy way for you to add a 1000 Mbps fiber optic uplink port to your Fast Ethernet switch. You can use the SFP to extend the distance of your network, build a high-speed backbone network between switches, or connect additional end nodes to the network, such as high-speed servers. Figure 2 shows an example of an SFP transceiver. Figure 2.
AT-FS708/POE Fast Ethernet Switch Installation Guide LEDs The Power and port LEDs on the front panel of the AT-FS708/POE Fast Ethernet switch switch display the switch and its port status information. Table 2 describes the Power LED. Table 2. Power LED LED PWR State Description Green The switch is powered ON. OFF The switch has no power. Each twisted-pair port has two LEDs, as described in Table 3. Table 3.
Chapter 1: Overview eco-friendly Button The front panel eco-friendly button is illustrated in Figure 3 below. It enables the eco-friendly low power mode feature. This mode allows you to conserve power by turning off the port LEDs when they are not required. Press the eco-friendly button next to the Power LED and shown in Figure 3 to toggle the LEDs on or off. The eco-friendly mode does not affect the network traffic on the switch or the Power LED. 1613 Figure 3.
AT-FS708/POE Fast Ethernet Switch Installation Guide Power Supply The AT-FS708/POE Fast Ethernet switch has an internal power supply with a single AC power supply socket on the back panel. To power the switch on or off, connect or disconnect the power cord provided with the switch. Note For the power requirements, refer to “Power Specifications” on page 49.
Chapter 1: Overview Power over Ethernet The twisted-pair ports on the AT-FS708/POE Fast Ethernet switch feature Power over Ethernet (PoE). PoE is a mechanism for supplying power to network devices over the same twisted-pair cables used to carry network traffic. This feature can simplify network installation and maintenance by allowing you to use the switch as a central power source for other network devices. A device that receives its power over an Ethernet cable is called a powered device (PD).
AT-FS708/POE Fast Ethernet Switch Installation Guide Power Budgeting The AT-FS708/POE Fast Ethernet switch provides a maximum power of 15.4 W per port on four of the eight ports for a total power consumption of 65 W, while at the same time furnishing standard 10/100 Mbps Ethernet functionality. The AT-FS708/POE smart power management functionality also supports any combination of Ethernet ports (1-8) that supply power for IEEE 802.
Chapter 1: Overview Implementation A standard Ethernet twisted-pair cable contains four pairs of strands for a total of eight strands. 10/100 Mbps network traffic requires only four strands (1, 2, 3, and 6), leaving four strands in the cable unused (4, 5, 7, and 8). The PoE standard, IEEE 802.3af, describes two alternative ways for delivering power to a powered device (PD) over twisted-pair cabling. Alternative A uses the same strands that carry the network traffic. Alternative B uses the spare strands.
AT-FS708/POE Fast Ethernet Switch Installation Guide Ethernet Switching Basics An Ethernet switch interconnects network devices, such as workstations, printers, routers, and other Ethernet switches, so that they can communicate with each other by sending and receiving Ethernet frames. MAC Address Table Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer.
Chapter 1: Overview Duplex Mode Duplex mode refers to how an end node receives and transmits data. If an end node can receive or transmit data, but not both simultaneously, the end node is operating in what is referred to as half-duplex mode. If an end node can both receive and transmit data simultaneously, the end node is said to be operating in full-duplex mode.
AT-FS708/POE Fast Ethernet Switch Installation Guide Store and Forward The AT-FS708/POE Fast Ethernet switch uses store and forward as the method for receiving and transmitting frames. When a Ethernet frame is received on a switch port, the switch does not retransmit the frame out the destination port until it has received the entire frame and stored the frame in a port buffer. It then examines the frame to determine if it is a valid frame.
